// this file contains the machine specific laptop power management stuff
// to add support for your own OS this is should be the only place you need
// to change - to add your own stuff insert above the line marked
// 'INSERT HERE' :
//
// #ifdef MY_OS"
// .. copy of linux code or whatever you want to use as a base
// # else
//
// then tag an extra '#endif' at the end
//
// There is support for the following OSsen right now:
//
// Linux (#if __linux__)
// FreeBSD (#elif __FreeBSD__)
// NetBSD (#elif __NetBSD_APM__)
// generic nothing (#else)
//
//
// The code here is written in a C rather than C++ like to encourage
// people more used to kernel types to do stuff here
//
// If you have any problems, questions, whatever please get in touch
